The Glow-worm 0020097328 Expansion Vessel is a genuine 8-litre replacement vessel designed to maintain stable water pressure within compatible Glow-worm boilers. As system water heats and expands, the expansion vessel absorbs the increased volume, preventing pressure spikes, leaks, and unnecessary strain on the boiler’s components.

A failing or waterlogged expansion vessel can cause repeated pressure loss, pressure relief valve discharge, noisy operation, or boiler lockouts. Replacing it with this genuine Glow-worm part restores reliable pressure regulation and smooth system performance.
